Vegetable Precooling Forced Air Cooler Multi Speed Controlled Energy Efficient

Forced - Air Coolers

ALLCOLD Forced Air Cooler’s innovative design has surpassed technologies used in previous designs. Older precooling equipment, sometimes referred to as Pressure Cooling or Cooling Tunnels, used chilled water as a secondary cooling medium to chill air, which inherently limited the air temperatures to above 34 degrees.

ALLCOLD uses a more efficient and direct method of air chilling to achieve shorter cooling times, further enhancing a longer shelf life of the product. Additionally, TRJ's Forced Air Coolers can function as precooling systems and room coolers for almost any fruit or vegetable. Some of the precooling systems shown below are forced air cooling units for precooling strawberries, bell peppers, and grapes, typically a high volume commodity.

Application Field

Forced Air Coolers are Suitable for:
Artichokes, Avocados, Green Beans, Brussels Sprouts, Cabbage, Cantaloupes, Cauliflower, Cherries, Cucumbers, Grapes, Honeydews, Kiwi, Nectarines, Okra, Onions (dry), Peaches, Bell Peppers, Plums, Summer Squash, Strawberries, Tomatoes and more.

Benefits of Forced - Air Cooling

To preserve quality, fresh produce should be cooled to its lowest safe (optimum) storage temperature as quickly as is practical and economical. Forced-air cooling is much faster than room cooling and is being used increasingly in North Carolina to cool produce quickly. It offers these advantages:

1. It decreases the time the produce remains at elevated temperatures, thereby reducing deterioration;
2. It results in shorter cooling times and thus more efficient use of the cooling facility;
3. It can cool produce effectively in a variety of unopened containers without wetting it or subjecting it to excessive handling;
4. It is often more energy efficient than room cooling when large volumes of produce must be cooled;
5. An available room-cooling facility with adequate cooling capacity can be converted to forced-air cooling with only a relatively small investment in fans

Features of Forced - Air Cooling

1. High surface area cooling coil

2. High air flow fan capacity

3. Galvanized steel housing for long term protection against corrosion

4. Optimum temperature differential to achieve desired relative humidity

5. Touchscreen controls with PLC

6. Multispeed control for room cooling conditions

7. Ammonia and “Freon” models available

8. Various defrosting options

Real Energy Saving!
The multispeed capability is a real energy saver over other single speed pre-cooling systems and can, in some cases, result in utility company rebates. Advanced temperature controls and PLC's on multiple systems are used to control the unit's functions, which are capable of interfacing with PC based plant management systems.

ALLCOLD precooling systems are complete with packaged refrigeration systems and cooling units, ready for field installation.
